A U.S. Border Patrol agent killed during a traffic stop near the Canadian border worked security duty at the Pentagon during the time of the Sept. 11 attacks.

Federal agents are investigating after a US Border Patrol agent was shot and killed Monday afternoon on the highway in Vermont.

The agent was identified as David “Chris” Maland, 44. Maland was a Blue Earth native and a graduate of Fairmont High School.

Agent David “Chris” Maland died in a shooting following a traffic stop, the FBI said. A second person killed in the incident was a German national in the country on a current visa, authorities said.

One suspect, a German national, is dead, and a second suspect, a U.S. citizen, suffered injuries, authorities said.

Governor Phil Scott identified David Maland as the fallen officer, extending his “heartfelt condolences to Agent Maland’s family, friends, and colleagues."
